Miniature rose plant named ‘JACyarp’

ABSTRACT

Miniature rose plant having flowers of novel color presented in large sprays, compact rounded growth habit, dark green foliage, and ease of rooting of softwood cuttings.

The present invention relates to a new and distinct variety of roseplant of the miniature class which was originated by me by crossing anunnamed seedling (not patented) with the variety JACpray (not patented).

The primary objective of this breeding was to produce a new rose varietyhaving the bright orange-pink blend color, compact habit and healthyfoliage of the female parent combined with the excellent bud form andclustering ability of the male parent. The objective was substantiallyachieved, along with other desirable improvements, as evidenced by thefollowing unique combination of characteristics that are outstanding inthe new variety and that distinguish it from its parents, as well asfrom all other varieties of which I am aware:

1. Compact, rounded plant habit;

2. Novel flower color;

3. Dark green, glossy foliage;

4. Flowers presented in large sprays; and

5. Ease of rooting from softwood cuttings.

Asexual reproduction of this new variety by cuttings, as performed atWasco, Calif., shows that the foregoing and all other characteristicsand distinctions come true to form and are established and transmittedthrough succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) colour chart, except where ordinarydictionary significance of color is indicated.

Parentage:

Seed parent.—Unnamed seedling (not patented).

Pollen parent.—JACpray (not patented).

FLOWER

Observations made from specimens grown in a garden environment at Somisin California, January, 1999 to August, 2000.

Blooming habit: Continuous.

Bud:

Size.—Half an inch long when the petals start to unfurl.

Form.—The bud form is long, pointed ovoid.

Color.—When sepals first divide, bud color is Red Group 46D on the budtip upper third; to Red Group 47C in the middle third; and near YellowGroup 8C on the lower third. When half blown, the upper sides of thepetals are Red Group 46D on the petal edge; changing to Red Group 47Dfrom the edge to middle of the petal; and near Yellow Group 8B on thelower third of the petal. The lower sides of the petals are Red Group46D on the petal edge, changing to Red Group 47D on the outer third ofthe petal and then to Yellow Group 8C on the rest of the petal.

Sepals.—Color: Green Group 138B with some Greyed-Purple Group 183D inareas exposed to bright sunlight. Surface texture: Covered in finehairs. There are three lightly appendaged sepals. There are twounappendaged sepals with hairy edges.

Receptacle.—Color: Green Group 139B with areas of Greyed-Purple Group183D in areas exposed to bright sunlight. Shape: Funnel. Size: Small,about ¼ inch×{fraction (3/16)} inch. Surface: Smooth with a few finehairs.

Peduncle.—Length: Short, averaging about 1 inch. Surface: Glandular.Color: Green Group 139C. Strength: Stiff, erect, slender.

Bloom:

Size.—Small. Average open size is 2 inches.

Borne.—Several together, in pyramidal clusters of 5-9 blooms.

Stems.—Strength: Strong. Average length is about 6-8 inches.

Form.—When first open: Bloom is high centered. Permanence: Flattens, allpetals curl.

Petalage.—Number of petals under normal conditions: 15-20.

Color.—The upper sides of the petals are Red Group 46D on the petaledge, changing to Red Group 47D from the petal edge to the middle of thepetals; the lower third of the petals being near Yellow Group 8B. Thereverse side of each petal is Red Group 46D on the petal edge, changingto Red Group 47D on the outer third of the petal, and then to YellowGroup 8D on the rest of the petal. The base of each petal has a small (⅛inch×{fraction (3/16)} inch) Yellow Group 8B spot on the upper surface.The lower surface has a small (⅛ inch×{fraction (3/16)} inch) spot ofYellow Group 8C. The major color on the upper sides is Red Group 47D.

Variegations.—There are occassional streaks on the guard petals close toGreen-White Group 157D.

Discoloration.—The general tonality at the end of the first day: Nochange. At the end of the third day: There is some change in overallcolor toward Red Group 47D on the petal edges. By day five, color fadesin overall impression to Red Group 50C. Petals drop by day six.

Fragrance.—Slight.

Petals:

Texture.—Thick, leathery.

Shape.—Round, to deltoid.

Form.—Tips slightly recurved.

Arrangement.—Imbricated. Petaloids in the center are few (only one ortwo) and are Red Group 47D, sometimes with a streak of Green-White Group157D.

Persistence.—Petals drop off cleanly.
